Application filed August 29. 1919. Serial No. 329,677.

To all fui 7.10m it' may concern.'

le it known that l, Bar-il, lt/lANsoN, a citizen oit the United States, residing at Rochester. in the county ot h/lonroe and State or New York, have invented certain new and use-ful lmprovements in lmpulse Trans init-ters, oli which the following,- is a full, clear, concise, and exact description.

This invention relates to impulse trans mitters, and more particularly to impulse transmitters vttor use in controlling directively operated automatic switches.

ln automatic telephone systems in which it was desired to use substation controlled it was previously necessary to have s; c. l desk stands and *e ll sets which were provided with a special push button or other means to control contacts in a signaling` circuit. Since it is not only undesirable to have several types ot desk stands and wall telephone sets, but since the addition of the push button to the sets was a source ot additional expense, is proposed in the present invention to so position the push button in relation to the impulse transmitter that the push button need not be mounted in the structure ot the desk stand itselt or ot the wall telephone set, but it is placed in the im pulse transmitter and is so placed with respect to the other parts of the impulse transmitter that will be convenient to operate, neat in appearance and yet will not in; tei-tere with the accurate transmission or current impulse Referring; to the drawings, Fig. 1 represents a 'liront view oii the impulse transmitting; device provided with a ringing' push button.

2 is a side view o t the impulse transmitting' device partially in cross section with certain parts broken away to more clearly disclose the t'eaturcs t1 nereot.

3 is a rear view ol the impulse transmitting' device oi this invention.

ln the drawings, 5 designates a circular frame plate which serves as a support 'tor the other parts ot the impulse tra emitter. This plate has a rim within which is placed asecond plate Gon which there may appear various designations, in the present instance the numerals 1 to O. rlhe plate is provided with a central opening in which there is secured a hollow hub '7, in which a hollow shaft 8 is adapted to rotate. ik linger-hold dial 9 is secured to the upper part of this shaft to rotate therewith and an instruction disk 10 lies on the upper surface ot the dial plate and is held in position by a nut threaded on the upper portion or the hollow sha-ft. A gear wheel 11 is mounted to rotate on the hollow shatt and has its upper surface provided with teeth to co-operate with a resilient dog; (not shown) carried by a Washer 26 and secured to thedial 9, so that when the dial 9 is rotated in the direction oi the stop 12, theresilient dog rides over the teethoii the ratchet wheel 11, permitting' this wheel to remain stationary, but when the dial rotates in a counter clockwise direction the resilient dog engages the teeth of the `ratchet wheel and causes it to rotate with the dial. small gear 13 engages the ratchet, wheel 11 and is rotated thereby. rllhis l`gear wheel is mounted on a shaft which is provided with a `second gear wheel 14 lenginging the worm 15 controlling a well known type of governor, and is also provided with impulse segments 16 which control the ope/nino; and closure ot the impulsespringrs 17. A spiral spring 18 surroundingthe hollowv shaft is secured at one end to the trame plate 5 and at its lower end to a pin 19. rllhis spring as is well known, is wound up when the dial is moved from normal and tends to restore the dial to .its original position. lifiounted on the pin 19 is a piece ot insulation, such as hard rubber, which holds the shunting` springs 20 open, except when the dial is moved trom normal position. A. rod 21 provided at one end vwith a ringing` button 22 is threaded through the hollow shaft and has a notch in its lower portion to receive the pin 19, to prevent the rod 21 )trom being removed 'from the transmitter. [it the extreme lower portion ot tho rod there is 'tastened a piece o'' insulationwhich enano; f* tho ringing; spring; 23, and when thc button 22 is depressed the spring` engages the spring; 24 to close contacts in a signaling circuit. The impulsins; springs 17, the shuntinp; springs 2O and the ringing,` springs 28 and 24tare suitably insulated trom each other and mounted on a spring assembly secured to frame plate 5 as shown in Fig. 2.

lllhen it is desired to .use the present impulse transmitter in a system wherein the ringing is not substation controlled, the springs 23 and 24 may be omitted from the spring assembly, and the rod 2l is likewise omitted. A blank disk may then be placed over the opening in the vhollow shaft.

` What l claim is y l. ln an impulsetransmitting device, a circular frame having a central opening', a numeral plate associated therewith, a shaft having a longitudinal opening, a dial secured to saidshaft arranged to be manuallyV rotated in a clockwise direction, a spring for rotating said shaft and dial in the reverse direction, a spring assembly'supported by saidframe and provided with sets of flat contact springs llying in parallel planes, means operativeduring the reverse 'movement' of said dial foractuating one of "said sets of springs land `a vrod provided with a button on `one end and insulation on the other, saidrod being movable through lthe opening in said shaft fork actuating ya sec- 'ond set vof springs. v
